19.3 Fault recovery procedures

29.0023GPPMobile Application Part (MAP) specificationRelease 17TS

When a location register has restarted after a fault, the fault recovery procedures ensure that the subscriber data in the VLR or in the SGSN become consistent with the subscriber data that are stored in the HLR for the MS concerned and that the location information in the HLR , the VLR and the SGSN reflect accurately the current location of the MS.

The stage 2 specification of fault recovery procedures in location registers is 3GPP TS 23.007 [19].
